Speaking from the White House Monday, Trump called the massacre "an act of pure evil." He praised first responders and police on scene for their bravery at the tragic scene.

"The speed with which they acted is miraculous, and prevented further loss of life," the president said. "To have found the shooter so quickly after the first shots were fired is something for which we will always be thankful and grateful."

The president has ordered all American flags across the country to be flown at half-staff until sunset on October 6th in honor of the victims of Las Vegas. In his remarks, Trump said that he will visit Las Vegas on Wednesday.

"In moments of tragedy and horror, America comes together as one. And it always has," Trump said. "Our unity cannot be shattered by evil" and "our bonds cannot be broken by violence."

Trump says he and First Lady Melania Trump are praying "for the entire nation to find unity and peace."

My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you!
